Using strong and targeted but noninvasive magnets at specific sites in the brains of people with and without mild learning and memory problems, Johns Hopkins researchers report they were able to detect differences in the concentrations of brain chemicals that transmit messages between neurons. The strength of these magnetic fields allows the researchers to measure

Columbia engineers and neuroscientists have joined forces to create 3D videos of individual nerve cells moving, stretching and switching on inside fruit fly larvae as they move. Data gleaned from these videos reveals how nerve cells called proprioceptive neurons work together to help the body sense where it is in space. To accomplish this feat,

Elizabeth Delacruz can’t crawl or toddle around like most youngsters nearing their second birthday. A rare metabolic disorder that decimated her mobility has also led to cortical blindness — her brain is unable to process images received from an otherwise healthy set of brown eyes. And multiple times a day Elizabeth suffers seizures that continually

Experts from the Basque research centre BCBL have shown for the first time that the way in which the activity of two brains is connected depends on whether the dialogue takes place in the native language or in a foreign language. As two people speak, their brains begin to work simultaneously, synchronizing and establishing a

Binge drinking in adolescence has been shown to have lasting effects on the wiring of the brain and is associated with increased risk for psychological problems and alcohol use disorder later in life. Now, researchers at the University of Illinois at Chicago Center for Alcohol Research in Epigenetics have shown that some of these lasting

More people today are poised to explore space than ever before; those who do will experience the effects of microgravity on the human body. Recognizing the need for more data related to those effects, Medical University of South Carolina (MUSC) neuroradiologist Donna Roberts, M.D., and co-author Lonnie G. Petersen, M.D.,Ph.D., University of California San Diego,

Getting enough of the omega 3 fatty acids DHA and EPA into the brain to study their effects on conditions such as Alzheimer’s and depression — which they have been shown to help — is no easy task. While supplements containing these fatty acids exist, there is scant evidence showing that these supplements actually increase

Academics at the University of Warwick have found that low functional connectivity of the lateral orbitofrontal cortex that is associated with the tendency to smoke is associated with increased impulsiveness — which may contribute to the tendency to smoke. The high connectivity of the reward-related medial orbitofrontal cortex in drinkers may increase the tendency to

Researchers at Sahlgrenska Academy at the University of Gothenburg, Sweden, in collaboration with research groups in Finland, Canada, and Slovenia, have discovered a novel and unexpected function of nestin, the best known marker of neural stem cells. In the developing brain, the 3 main cell types, specifically neurons, astrocytes and oligodendrocytes, are generated from neural

The rat in a maze may be one of the most classic research motifs in brain science, but a new innovation described in Cell Reports by an international collaboration of scientists shows just how far such experiments are still pushing the cutting edge of technology and neuroscience alike. In recent years, scientists have shown that

That moment when you step on the gas pedal a split second before the light changes, or when you tap your toes even before the first piano note of Camila Cabello’s “Havana” is struck. That’s anticipatory timing. One type relies on memories from past experiences. The other on rhythm. Both are critical to our ability

Researchers from the Netherlands Institute for Neuroscience and Amsterdam UMC have disclosed the nature of how T cells protect the brain against harmful viruses. The results of the study, which are published in Nature Communications, are important for investigating the role of the immune system in numerous brain disorders. Immune system The immune system protects

Nearly 30 years ago, scientists demonstrated that visually recognizing an object, such as a cup, and performing a visually guided action, such as picking the cup up, involved distinct neural processes, located in different areas of the brain. A new study shows that the same is true for how the brain perceives our environment —

Spinal cord stimulation and physical therapy have helped a man paralyzed since 2013 regain his ability to stand and walk with assistance. The results, achieved in a research collaboration between Mayo Clinic and UCLA, are reported in Nature Medicine. With an implanted stimulator turned on, the man was able to step with a front-wheeled walker

Human papillomavirus (HPV) is widely known to cause nearly all cases of cervical cancer. However, you might not know that HPV also causes 70 percent of oropharyngeal cancer, a subset of head and neck cancers that affect the mouth, tongue, and tonsils. Although vaccines that protect against HPV infection are now available, they are not

By developing a novel decoding technology, a team of engineers and physicians at the University of Southern California (USC) and UC San Francisco have discovered how mood variations can be decoded from neural signals in the human brain — a process that has not been demonstrated to date. Their study, published in Nature Biotechnology, is

Ever wonder why some people seem to feel less pain than others? A study conducted at Wake Forest School of Medicine may have found one of the answers — mindfulness. “Mindfulness is related to being aware of the present moment without too much emotional reaction or judgment,” said the study’s lead author, Fadel Zeidan, Ph.D.,

The brains of professional beatboxers and guitarists respond to music differently when compared to each other and non-musicians, finds a new UCL-led study. The study, published in Cerebral Cortex and funded by Wellcome, sheds light on how learning and making music can affect mental processes. The researchers found that the area of the brain that

Figuring out how to make articles and videos go viral is the holy grail for any content creator. Although a magic formula remains elusive, in recent years, neuroscientists have forecasted which content will go viral by showing it to a small number of people and observing their brain activity. Now, they’ve taken that research a

Most animals have a keen sense of smell, which assists them in everyday tasks. Now, a new study led by researchers at NYU School of Medicine sheds light on exactly how animals follow smells. Published online in the journal eLife on Aug. 21, the study measured the behavior of fruit flies as they navigated through
